I've looked through 0004-0007. I've only found the following: (5) 0005 With this read-only option type, application can connect to connecting to a read-only server in the list of hosts, in case if there is any read-only servers available, the connection attempt fails.
"connecting to" can be removed. in case if there is any read-only servers -> If There's no read only server Regards Takayuki Tsunakawa
